Hey guys I was just hoping someone with more knowledge on the subject could chime in on what's happening. I have a launch day IPhone 7 with T-Mobile service. At my home I have noticed my phone on average has 2 dots of reception when on standby and normal internet surfing. However when making a call my service jumps to 4 to 5 dots every time. Having two dots still gives me great LTE speeds so it isn't a problem. What's causing this? Is my phone throwing less juice to my antenna when it's not nessary for full power reception?
